There are other ways to do it. I have someone plugged in right now to my
proxy, using her employer's wireless network and her own laptop, connecting
to one of several chat networks where I operate chat room for my online
radio
station. She works at a gym, and the credit card processing system is on a
DSL
connection, and on WiFi,. so when she works in the office, she just connects
her laptop to her employer's WiFi access point and then connects to my
proxy,
so the router logs will show that somoene went to my proxy, but nothing
beyond
that.

She is also on one "adult" chat room right now, where she told me she does
this, and her employer has no CLUE as to what she is up to. She works
the night shift at a 24-hour gym, so she brings her laptop, and connects
to her favourite chat room, as well as my online radio station, and the boss
has no as to what is happening at night around there. The boss will see
that someone connected to my proxy, but where anyone went BEYOND
that point will NEVER be known.
